Anju T Sudhakar 33583e6950 perf tools powerpc: Add support for extended register capability ... Add extended regs to sample_reg_mask in the tool side to use with `-I?` option. Perf tools side uses extended mask to display the platform supported register names (with -I? option) to the user and also send this mask to the kernel to capture the extended registers in each sample. Hence decide the mask value based on the processor version. Currently definitions for `mfspr`, `SPRN_PVR` are part of `arch/powerpc/util/header.c`. Move this to a header file so that these definitions can be re-used in other source files as well.
